Description

本発明はテレビジョン放送信号を受信するテレビジョン放送信号受信装置に関する。   The present invention relates to a television broadcast signal receiving apparatus that receives a television broadcast signal.

近年、放送の多チャンネル化によるチャンネル数の増加に伴い、ユーザがチャンネルを選局する際の操作が複雑になってきている。例えば、従来のテレビジョン放送信号受信装置（以下、ＴＶ放送信号受信装置という）では、ユーザは、視聴するチャンネルを選択する際、１００を超えるチャンネル数の中から所望するチャンネルのチャンネル番号をテンキー等を用いて入力する必要があり、複数の操作手順を要していた。通常、ユーザがこれら多くのチャンネルを満遍なく視聴することは稀であり、頻繁に視聴するチャンネルは限られているため、視聴頻度の高いチャンネルのみを簡単に選局操作することができるようにすることが望まれている。   In recent years, with the increase in the number of channels due to the increase in the number of broadcast channels, operations when a user selects a channel have become complicated. For example, in a conventional television broadcast signal receiving apparatus (hereinafter referred to as a TV broadcast signal receiving apparatus), when a user selects a viewing channel, the channel number of a desired channel is selected from the number of channels exceeding 100 using a numeric keypad or the like. It was necessary to input using a plurality of operation procedures. Normally, users rarely view these many channels evenly, and the channels that are frequently viewed are limited, so that only the channels with the highest viewing frequency can be easily selected. Is desired.

ところで、視聴頻度の高いチャンネルを簡単に選局できるようにしたＴＶ放送信号受信装置として、電源投入時等において、視聴頻度の高いチャンネルを自動的に選局するようにした装置が知られている（例えば、特許文献１及び特許文献２参照）。   By the way, as a TV broadcast signal receiving apparatus that can easily select a channel with high viewing frequency, an apparatus that automatically selects a channel with high viewing frequency when the power is turned on is known. (For example, refer to Patent Document 1 and Patent Document 2).

また、ピクチャ・イン・ピクチャ（ＰｉｎＰ）機能等、１つの表示画面に複数の異なるチャンネルの映像を表示する複数映像表示機能を備えたＴＶ放送信号受信装置において、子画面等として表示されるチャンネルを、そのチャンネルの視聴頻度等に応じて表示するようにした装置等も知られている（例えば、特許文献３乃至特許文献６参照）。

JP-A-3-214919 JP-A-4-207718 JP-A-4-77109 JP-A-8-140003 JP-A-8-181927 JP 2000-333094 A

しかしながら、上記特許文献１及び特許文献２に記載される装置は、電源投入時等において視聴頻度の高いチャンネルを自動的に選局することができるようにしたものであって、ユーザが自発的に視聴頻度の高いチャンネルを選局できるようにしたものではない。このため、例えば、ユーザが普段よく見るチャンネルでどのようなＴＶ番組が放送されているか確認する場合など、視聴頻度が高いチャンネルを順番に選局する場合などの操作性を改善できるものではなかった。   However, the devices described in Patent Document 1 and Patent Document 2 can automatically select a channel having a high viewing frequency when the power is turned on, and the user voluntarily selects the channel. It is not designed to select a channel with high viewing frequency. For this reason, it has not been possible to improve the operability when, for example, selecting a channel with a high viewing frequency in order, for example, when checking what TV program is being broadcast on a channel that the user often watches. .

また、上記特許文献３乃至特許文献６に記載される装置は、ＰｉｎＰ機能を有する装置を前提としており、高いグラフィック処理能力を有する高価なマイコンが必要になる。また、これらの装置では、選局するチャンネルを選択する際、まず、カーソルキーを操作して選局するチャンネルの子画面を選択し、決定キーを操作して選局するチャンネルを決定する等、視聴するチャンネルを選局する際、複数のキーを操作する必要があった。   The devices described in Patent Documents 3 to 6 are based on a device having a PinP function, and an expensive microcomputer having high graphic processing capability is required. In these devices, when selecting a channel to be selected, first, the cursor key is operated to select a sub-screen of the channel to be selected, the determination key is operated to determine the channel to be selected, etc. When selecting a channel for viewing, it was necessary to operate a plurality of keys.

一方、このような操作性を改善する一つ手段として、ユーザに、予め視聴頻度の高いチャンネルをお気に入りのチャンネルとして登録（以下、単に「お気に入り」に登録という）させ、チャンネルの選局時に、この登録を呼び出すことにより視聴頻度の高いチャンネルを選局できるようにする方法等が考えられる。   On the other hand, as one means for improving such operability, a user registers a channel with high viewing frequency as a favorite channel in advance (hereinafter simply referred to as “favorite”), and when selecting a channel, A method of allowing a channel with a high viewing frequency to be selected by calling up registration is conceivable.

しかしながら、このような方法では、ユーザ自らがチャンネルを「お気に入り」として登録する必要があり、ユーザに登録作業を強いることとなる。また、ユーザが「お気に入り」の機能自体、理解できない虞もある。   However, such a method requires the user himself / herself to register the channel as a “favorite”, which forces the user to register. In addition, the user may not understand the “favorite” function itself.

本発明は、上記課題を解決するためになされたものであり、視聴頻度が高いチャンネルを、簡単な操作で選局することができるテレビジョン放送信号受信装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a television broadcast signal receiving apparatus capable of selecting a channel with a high viewing frequency by a simple operation.

In the signal receiving device, when the same channel is continuously selected for a predetermined time or more by the channel selection unit, the viewing points are counted one point at a time for each predetermined time, and the viewing history of each channel is recorded as the number of viewing points. Viewing point calculation means for calculating as follows; viewing history storage means for storing the number of viewing points for each channel selected by the channel selection means; and the number of viewing points stored in the viewing history storage means. Based on this, for each predetermined period, the number of viewing points for a predetermined period is totaled for each channel, and only channels whose total viewing points are higher than a predetermined value are extracted. Then, the viewing frequency rank calculating means for calculating the viewing frequency rank of these channels, the viewing frequency rank storing means for storing the viewing frequency rank calculated by the viewing frequency rank calculating means, and the channel having the highest viewing frequency in order. Channel selection operation means operated by a user when selecting a channel, and the channel selection control means is stored in the viewing frequency rank storage means when the channel selection operation means is operated by a user. The channel selection operation is controlled based on the stored viewing frequency ranking, and each time the channel selection operation means is operated, the channel is selected in order from the channel with the highest total viewing points, and the number of viewing points is set. Channel selection based on the channel selection operation means is omitted for channels whose total is equal to or less than the predetermined value.

請求項２の発明は、指定されたチャンネルの選局を行う選局手段と、前記選局手段による選局動作を制御する選局制御手段とを備えたテレビジョン放送信号受信装置において、前記選局手段で選局された各チャンネルの視聴履歴を記憶する視聴履歴記憶手段と、前記視聴履歴記憶手段に記憶された各チャンネルの視聴履歴に基づいて、視聴頻度が所定値より高いチャンネルのみを抽出して、これらチャンネルの視聴頻度順位を算出する視聴頻度順位算出手段と、視聴頻度が高いチャンネルから順番にチャンネルを選局する際にユーザによって操作される選局操作手段と、を備え、前記選局制御手段は、ユーザによって前記選局操作手段が操作された際に、前記視聴頻度順位算出手段により算出された前記視聴頻度順位に基づいて選局動作を制御し、前記選局操作手段が操作される毎に、前記視聴頻度が高いチャンネルから順番に選局させ、前記視聴頻度が前記所定値以下のチャンネルについては該選局操作手段に基づく選局を省略したことを特徴とする。   According to a second aspect of the present invention, there is provided a television broadcast signal receiving apparatus comprising: a channel selection unit that selects a specified channel; and a channel selection control unit that controls a channel selection operation performed by the channel selection unit. Based on the viewing history storage means for storing the viewing history of each channel selected by the station means and the viewing history of each channel stored in the viewing history storage means, only channels whose viewing frequency is higher than a predetermined value are extracted. A viewing frequency rank calculating means for calculating the viewing frequency ranking of these channels, and a channel selection operating means operated by a user when selecting a channel in order from the channel with the highest viewing frequency. The station control means controls the channel selection operation based on the viewing frequency rank calculated by the viewing frequency rank calculation means when the channel selection operation means is operated by a user. Then, each time the channel selection operation means is operated, the channel is selected in order from the channel with the highest viewing frequency, and the channel selection based on the channel selection operation unit is omitted for the channel whose viewing frequency is the predetermined value or less. It is characterized by that.

請求項３の発明は、請求項２に記載のテレビジョン放送信号受信装置において、前記選局手段で同じチャンネルが所定時間以上連続して選局された場合に、該所定時間毎に視聴ポイントを１ポイントずつカウントして、各チャンネルの視聴履歴を視聴ポイント数として算出する視聴ポイント算出手段を備え、前記視聴履歴記憶手段は、前記選局手段で選局された各チャンネルごとに、前記視聴ポイント数を記憶することを特徴とする。   According to a third aspect of the present invention, in the television broadcast signal receiving device according to the second aspect, when the same channel is continuously selected for a predetermined time or more by the channel selection means, a viewing point is set every predetermined time. Viewing point calculation means for counting each point and calculating the viewing history of each channel as the number of viewing points, the viewing history storage means for each channel selected by the channel selection means, It is characterized by memorizing numbers.

以上のように請求項１の発明によれば、視聴履歴記憶手段に記憶された各チャンネルの視聴ポイント数に基づいて視聴頻度順位を算出し、ユーザによって選局操作手段が操作された際に、この視聴頻度順位に基づいて視聴頻度が高いチャンネルから順番に選局させ、視聴頻度が所定値以下のチャンネルについては選局操作手段に基づく選局を省略したので、ユーザは複雑な操作をすることなく選局操作手段を操作するだけで、視聴頻度が高いチャンネルのみを選局することができる。   As described above, according to the first aspect of the present invention, the viewing frequency ranking is calculated based on the number of viewing points of each channel stored in the viewing history storage unit, and when the channel selection operation unit is operated by the user, Channels are selected in order from the channel with the highest viewing frequency based on this viewing frequency ranking, and channel selection based on the channel selection operation means is omitted for channels with a viewing frequency of a predetermined value or less, so the user must perform complex operations. Only by operating the channel selection operation means, it is possible to select only channels with high viewing frequency.

また、視聴履歴記憶手段に記憶された各チャンネルの視聴履歴に基づいて視聴頻度順位が算出され、この視聴頻度順位に基づいて、選局操作手段が操作された際に行われる選局動作が制御されるので、視聴頻度の高いチャンネルを「お気に入り」として登録させる等の特別な作業をユーザに強いることなく、ユーザは選局操作手段を操作するだけで簡単に視聴頻度の高いチャンネルを選局することができる。   Also, the viewing frequency ranking is calculated based on the viewing history of each channel stored in the viewing history storage means, and the channel selection operation performed when the channel selection operation means is operated is controlled based on this viewing frequency ranking. Therefore, without forcing the user to perform a special operation such as registering a channel with high viewing frequency as a “favorite”, the user simply selects a channel with high viewing frequency simply by operating the channel selection operation means. be able to.

また、同じチャンネルが所定時間以上連続して視聴された場合にのみ視聴ポイントを１ポイントずつカウントして各チャンネルの視聴履歴を記憶するので、選局された各チャンネルの回数をカウントすることにより視聴履歴を記憶する場合と比べて、本来、視聴履歴としてカウントされるべきではないザッピング（テレビコマーシャル等の最中にチャンネルを次々と変える行為）等による選局が視聴履歴としてカウントされることを防止することができる。また、視聴頻度をポイント化して所定時間毎にカウントすることで、視聴した時間をそのまま視聴履歴として記憶する場合と比べて、記憶すべき情報量を削減することができる。   Also, only when the same channel is viewed continuously for a predetermined time or more, the viewing points are counted one by one and the viewing history of each channel is stored, so viewing by counting the number of times each channel is selected Compared to the case of storing history, channel selection due to zapping (an act of changing channels one after another during TV commercials) that should not be counted as viewing history is prevented from being counted as viewing history. can do. Also, by making the viewing frequency a point and counting every predetermined time, the amount of information to be stored can be reduced compared to the case where the viewing time is stored as it is as a viewing history.

また、視聴頻度順位は、所定周期毎に、所定期間分の視聴ポイント数を合計することにより算出され視聴頻度順位記憶手段に記憶されているので、ユーザによって選局操作手段が操作される毎に、改めて視聴頻度順位を算出するための処理を実行する必要がなく、選局操作手段に基づく選局動作時の処理負担を軽くすることができる。   Also, the viewing frequency rank is calculated by summing the number of viewing points for a predetermined period for each predetermined period, and is stored in the viewing frequency rank storage means. Therefore, every time the channel selection operation means is operated by the user. Therefore, it is not necessary to execute the process for calculating the viewing frequency ranking again, and the processing load during the channel selection operation based on the channel selection operation means can be reduced.

請求項２の発明によれば、ユーザによって選局操作手段が操作された際、視聴頻度順位に基づいて視聴頻度が高いチャンネルから順番に選局させ、視聴頻度が所定値以下のチャンネルについては選局操作手段に基づく選局を省略したので、ユーザは複雑な操作をすることなく選局操作手段を操作するだけで、視聴頻度が高いチャンネルのみを選局することができる。また、視聴頻度の高いチャンネルを簡単に選局できるようにするために、ユーザに特別な作業を強いることもない。   According to the second aspect of the present invention, when the channel selection operation means is operated by the user, the channel is selected in order from the channel with the highest viewing frequency based on the viewing frequency ranking, and the channel with the viewing frequency of the predetermined value or less is selected. Since channel selection based on the station operation means is omitted, the user can select only a channel with high viewing frequency by operating the channel selection operation means without performing complicated operations. In addition, the user is not forced to perform a special operation in order to easily select a channel with a high viewing frequency.

請求項３の発明によれば、同じチャンネルが所定時間以上連続して視聴された場合にのみ視聴ポイントを１ポイントずつカウントして各チャンネルの視聴履歴を記憶するので、選局された各チャンネルの回数をカウントすることにより視聴履歴を記憶する場合と比べて、ザッピング等による選局が視聴履歴としてカウントされることを防止することができると共に、視聴した時間をそのまま視聴履歴として記憶する場合と比べて、記憶すべき情報量を削減することができる。   According to the invention of claim 3, only when the same channel is continuously viewed for a predetermined time or more, the viewing points are counted one by one and the viewing history of each channel is stored. Compared to storing the viewing history by counting the number of times, it is possible to prevent channel selection due to zapping or the like from being counted as the viewing history, and compared to the case where the viewing time is stored as it is as the viewing history. Thus, the amount of information to be stored can be reduced.

制御部１８は、不図示のＲＯＭに記憶されているプログラムに従って各種処理を実行して装置全体を制御し、後述する選局制御処理を実行することによりチューナ１１による選局動作を制御して選局制御手段として機能する。また、制御部１８は視聴ポイント加算処理を実行することにより、チューナ１１で同じチャンネルが所定時間以上連続して選局された場合に、該所定時間毎に視聴ポイントを１ポイントずつカウントして、各チャンネルの視聴履歴を視聴ポイント数として算出する視聴ポイント算出手段として機能する。また、制御部１８は視聴頻度リスト作成処理を実行することにより、メモリ１７に記憶された視聴ポイント数に基づいて、所定周期毎に、各チャンネルについて所定期間分の視聴ポイント数を合計し、この視聴ポイント数の合計が所定値より高いチャンネルのみを抽出して、これらチャンネルの視聴頻度順位を算出する視聴頻度順位算出手段として機能する。   The control unit 18 executes various processes according to a program stored in a ROM (not shown) to control the entire apparatus, and controls the channel selection operation by the tuner 11 by executing a channel selection control process described later. Functions as station control means. In addition, the control unit 18 executes the viewing point addition process so that when the same channel is continuously selected for a predetermined time or more in the tuner 11, the viewing point is counted one point at a time for each predetermined time, It functions as viewing point calculation means for calculating the viewing history of each channel as the number of viewing points. In addition, the control unit 18 executes the viewing frequency list creation process to sum the number of viewing points for a predetermined period for each channel based on the number of viewing points stored in the memory 17. It functions as a viewing frequency rank calculating means for extracting only channels whose total number of viewing points is higher than a predetermined value and calculating the viewing frequency rank of these channels.

次に、視聴ポイント加算処理について図２を参照して説明する。視聴ポイント加算処理は、チューナ１１で任意のチャンネルが選局されている間、常に実行される。制御部１８は、ユーザによりテンキー４１又は視聴頻度順選局ボタン４２が操作されてチューナ１１で選局されているチャンネルが変更されたか否か監視し（＃１）、チャンネルが変更されると（＃１でＹＥＳ）、タイマーの値を”０”にリセットする（＃２）。そして、タイマーの値が１５分（所定時間）以上か否か判断する（＃３）。タイマーの値が１５分より小さければ（＃３でＮＯ）、ステップ＃１に戻ってタイマーの値が１５分以上になるまで、チャンネルが変更されたか否か監視する。そして、タイマーの値が１５分以上になると（＃３でＹＥＳ）、チューナ１１で選局されているチャンネルの視聴ポイントをインクリメントし、ステップ＃２に戻ってタイマーをリセットする（＃４）。   Next, viewing point addition processing will be described with reference to FIG. The viewing point addition process is always executed while an arbitrary channel is selected by the tuner 11. The control unit 18 monitors whether or not the channel selected by the tuner 11 is changed by operating the numeric keypad 41 or the viewing frequency order selection button 42 by the user (# 1), and when the channel is changed (# 1). If the answer is # 1), the timer value is reset to "0" (# 2). Then, it is determined whether the timer value is 15 minutes (predetermined time) or more (# 3). If the timer value is smaller than 15 minutes (NO in # 3), the process returns to step # 1 to monitor whether the channel has been changed until the timer value becomes 15 minutes or more. When the timer value is 15 minutes or more (YES in # 3), the viewing point of the channel selected by the tuner 11 is incremented, and the process returns to step # 2 to reset the timer (# 4).

制御部１８は、このような処理を繰り返すことにより、連続して選局された時間が１５分より小さくなるチャンネルについては視聴ポイントをカウントせず、同じチャンネルが連続して選局されている間は、１５分毎に視聴ポイントをカウントする。   By repeating such processing, the control unit 18 does not count viewing points for channels that are continuously selected for less than 15 minutes, while the same channel is continuously selected. Counts viewing points every 15 minutes.

なお、視聴ポイントを加算する間隔は１５分でなくてもよく、例えば、この間隔をテレビコマーシャルが挿入される間隔より短く設定することにより、テレビコマーシャル中だけチャンネルが変更された場合であっても、チャンネルが変更される前に視聴されていたテレビ番組のチャンネルついて視聴ポイントをカウントすることができる。   Note that the interval at which viewing points are added may not be 15 minutes. For example, by setting this interval to be shorter than the interval at which a television commercial is inserted, the channel may be changed only during the television commercial. , The viewing points can be counted for the channel of the TV program that was viewed before the channel was changed.

上記処理により算出された視聴ポイントは日付毎に管理され、所定期間分の視聴ポイント５０が常にメモリ１７内に記憶される。例えば、図３及び図４に示されるように、３月１１日の時点おいては、当日（３月１１日）に記憶される視聴ポイント５０の他に、３月４日〜３月１０日の７日（所定期間）分の視聴ポイント５０がメモリ１７内に記憶されている。このように、所定期間に区切って視聴ポイント５０をメモリ１７内に記憶することにより、視聴履歴を管理するために必要なメモリ１７の容量を削減することができる。また、７日分の視聴ポイント５０をメモリ１７に記憶して視聴履歴を管理することにより、1週間のサイクルで放送されるテレビ番組に合わせた視聴履歴の管理が可能となる。   The viewing points calculated by the above process are managed for each date, and viewing points 50 for a predetermined period are always stored in the memory 17. For example, as shown in FIG. 3 and FIG. 4, at the time of March 11, in addition to the viewing point 50 stored on that day (March 11), March 4 to March 10 The viewing points 50 for seven days (predetermined period) are stored in the memory 17. Thus, by storing the viewing points 50 in the memory 17 divided into predetermined periods, the capacity of the memory 17 necessary for managing the viewing history can be reduced. Further, by managing the viewing history by storing the viewing points 50 for 7 days in the memory 17, the viewing history can be managed in accordance with the television program broadcast in a one-week cycle.

次に、視聴ポイント５０に基づいて視聴頻度リスト６０を作成する際に行われる視聴頻度リスト作成処理について図５のフローチャートを参照して説明する。制御部１８は、時計回路１６からの出力に基づいて時刻を監視し、時刻が例えば午前０時０分になると（すなわち、１日１回の周期（所定周期）で）、視聴頻度リスト作成処理を開始する。視聴頻度リスト作成処理が開始されると、制御部１８は、まず、８日前の視聴ポイントを削除する（＃２１）。例えば、図３の例では、３月１１日の０時０分（同図の点Ａ）になると、３月３日の視聴ポイントを削除する。次に、１日前から７日前まで（所定期間分）の各チャンネルの視聴ポイント数の合計を算出する（＃２２）。図３及び図４の例では、３月４日から３月１０日までの各チャンネルの視聴ポイント数の合計を算出する。そして、視聴ポイント数の合計が所定値より高いチャンネルのみを抽出して、これらチャンネルの視聴頻度順位を算出し、視聴頻度リスト６０を作成する（＃２３）。図６に示す例では、視聴ポイント数の合計が”１９”ポイントより高くなるチャンネルのみを抽出して視聴頻度リスト６０を作成し、視聴ポイント数の合計が高くなるチャンネルから順番に視聴頻度順位”１”〜”５”を割り当てている。なお、視聴頻度リスト６０に登録するチャンネル数を任意の数に限定するなどしてもよい。図３に示されるように、本実施形態においては、視聴頻度リスト作成処理は１日のうちで０時０分のタイミングでのみ行われるので、３月１１日の０時０分（点Ａ）より後、３月１２日の０時０分（点Ｂ）までは視聴ポイント５０はカウントされるが、視聴頻度リスト６０は更新されることはない。   Next, viewing frequency list creation processing that is performed when the viewing frequency list 60 is created based on the viewing points 50 will be described with reference to the flowchart of FIG. The control unit 18 monitors the time based on the output from the clock circuit 16, and when the time reaches, for example, 0:00 (that is, once a day (predetermined cycle)), the viewing frequency list creation process To start. When the viewing frequency list creation process is started, the control unit 18 first deletes the viewing point 8 days ago (# 21). For example, in the example of FIG. 3, the viewing point on March 3 is deleted at 0:00 on March 11 (point A in the figure). Next, the total number of viewing points of each channel from one day ago to seven days ago (for a predetermined period) is calculated (# 22). In the example of FIG. 3 and FIG. 4, the total number of viewing points of each channel from March 4 to March 10 is calculated. Then, only the channels whose total number of viewing points is higher than a predetermined value are extracted, the viewing frequency ranking of these channels is calculated, and the viewing frequency list 60 is created (# 23). In the example shown in FIG. 6, the viewing frequency list 60 is created by extracting only the channels with the total number of viewing points higher than “19” points, and the viewing frequency ranking is started in order from the channel with the highest number of viewing points. 1 "to" 5 "are assigned. Note that the number of channels registered in the viewing frequency list 60 may be limited to an arbitrary number. As shown in FIG. 3, in this embodiment, the viewing frequency list creation process is performed only at the time of 0:00 of the day, so 0:00 on March 11 (point A). Later, until 00:00 (point B) on March 12, the viewing point 50 is counted, but the viewing frequency list 60 is not updated.

次に、選局制御処理について図７のフローチャートを参照して説明する。制御部１８は、リモコン装置１４のテンキー４１又は視聴頻度順選局ボタン４２が操作されたか否か監視し、テンキー４１又は視聴頻度順選局ボタン４２が操作されると、選局制御処理を開始する。制御部１８は、選局制御処理が開始されると、まず、これから行われる選局処理がテンキー４１に基づくものか、視聴頻度順選局ボタン４２に基づくものか判断し（＃４１）、テンキー４１に基づくものであれば（＃４１でＮＯ）、テンキー４１を介して入力されたチャンネル番号に対応するチャンネルをチューナ１１に選局させ（＃４２）、優先度カウンタの値を”０”にリセットする（＃４６）。   Next, the channel selection control process will be described with reference to the flowchart of FIG. The control unit 18 monitors whether or not the numeric keypad 41 or the viewing frequency order selection button 42 of the remote control device 14 is operated, and starts the channel selection control process when the numeric keypad 41 or the viewing frequency order selection button 42 is operated. To do. When the channel selection control process is started, the control unit 18 first determines whether the channel selection process to be performed is based on the numeric keypad 41 or based on the viewing frequency order selection button 42 (# 41). 41 (NO in # 41), the tuner 11 is tuned to the channel corresponding to the channel number input via the numeric keypad 41 (# 42), and the priority counter value is set to “0”. Reset (# 46).

一方、これから行われる選局処理が視聴頻度順選局ボタン４２に基づくものであれば（＃４１でＹＥＳ）、優先度カウンタの値がインクリメントされ（＃４３）、優先度カウンタの値に基づいて選局するチャンネルが決定され、選局される（＃４４）。前回の選局処理がテンキー４１に基づくものであれば（＃４１でＮＯ）、ステップ＃４６において優先度カウンタがリセットされているので、ステップ＃４４における優先度カウンタの値は”１”（ステップ＃４３でインクリメントされている）となり、例えば、図６の視聴頻度リスト６０で視聴頻度順位の値と優先度カウンタの値が”１”で一致する２チャンネルが選局される（＃４４）。そして、制御部１８は、優先度カウンタの値が最大値になったか否か判断し（＃４５）、優先度カウンタの値が最大値になっていれば（＃４５でＹＥＳ）、優先度カウンタの値をリセットし（＃４６）、優先度カウンタの値が最大値になっていなければ（＃４５でＮＯ）、そのまま処理を終了する。なお、優先度カウンタの最大値は、例えば、視聴頻度リスト６０に登録されているチャンネル数により決定され、図６の例では優先度カウンタの最大値は”５”となる。   On the other hand, if the channel selection process to be performed is based on the viewing frequency order selection button 42 (YES in # 41), the value of the priority counter is incremented (# 43), and based on the value of the priority counter The channel to be selected is determined and selected (# 44). If the previous channel selection process is based on the numeric keypad 41 (NO in # 41), since the priority counter is reset in step # 46, the value of the priority counter in step # 44 is "1" (step For example, in the viewing frequency list 60 of FIG. 6, two channels that match the value of the viewing frequency ranking and the value of the priority counter with “1” are selected (# 44). Then, the control unit 18 determines whether or not the value of the priority counter reaches the maximum value (# 45). If the value of the priority counter reaches the maximum value (YES in # 45), the priority counter Is reset (# 46), and if the value of the priority counter is not the maximum value (NO in # 45), the process is terminated. Note that the maximum value of the priority counter is determined by, for example, the number of channels registered in the viewing frequency list 60, and the maximum value of the priority counter is “5” in the example of FIG.

図６の例において、視聴頻度順選局ボタン４２に基づいて視聴頻度順位が”１”となる２チャンネルが選局された状態（この状態では、優先度カウンタの値は”１”）で、再度、視聴頻度順選局ボタン４２が押下されると、ステップ＃４２において、優先度カウンタの値がインクリメントされて”２”となり、視聴頻度順位”２”の３２チャンネルが選局される。また、視聴頻度順選局ボタン４２が連続して操作され、視聴頻度順位が”５”となる１０チャンネルが選局された状態（この状態では、優先度カウンタの値はステップ＃４６でリセットされているので”０”）で、再度、視聴頻度順選局ボタン４２が押下されると、ステップ＃４２において、優先度カウンタがインクリメントされて”１”となり、２チャンネルが選局される。このように視聴頻度順選局ボタン４２を連続して操作することにより、図８に示されるように、２チャンネル、３２チャンネル、５５チャンネル、４６チャンネル、及び１０チャンネルがサイクリックに選局され、これらチャンネルの映像がモニタ画面３に表示される。   In the example of FIG. 6, in a state where two channels having a viewing frequency ranking of “1” are selected based on the viewing frequency order selection button 42 (in this state, the value of the priority counter is “1”), When the viewing frequency order selection button 42 is pressed again, in step # 42, the priority counter value is incremented to "2", and the 32 channels of the viewing frequency ranking "2" are selected. In addition, the channel selection button 42 in the order of viewing frequency is continuously operated, and the channel 10 in which the viewing frequency ranking is “5” is selected (in this state, the value of the priority counter is reset in step # 46). Therefore, when the viewing frequency order selection button 42 is pressed again, in step # 42, the priority counter is incremented to "1" and two channels are selected. By continuously operating the viewing frequency order selection button 42 in this way, as shown in FIG. 8, the 2nd channel, the 32nd channel, the 55th channel, the 46th channel, and the 10th channel are cyclically selected, Images of these channels are displayed on the monitor screen 3.

制御部１８は、上記処理を実行することにより、ユーザによって視聴頻度順選局ボタン４２が操作された際に、メモリ１７に記憶された視聴頻度リスト６０の視聴頻度順位に基づいて選局動作を制御し、視聴頻度順選局ボタン４２が操作される毎に、視聴ポイント数の合計が高いチャンネルから順番（すなわち、視聴頻度順位が高い順番）に選局させ、視聴ポイント数の合計が所定値以下のチャンネル（すなわち、視聴頻度リスト６０に登録されてないチャンネル）については視聴頻度順選局ボタン４２に基づく選局を省略する。   The control unit 18 performs the above-described processing so that the channel selection operation is performed based on the viewing frequency ranking of the viewing frequency list 60 stored in the memory 17 when the user selects the viewing frequency order selection button 42 by the user. Every time the channel selection button 42 is controlled, the channel is selected in order from the channel with the highest number of viewing points (that is, the order with the highest viewing frequency ranking), and the total number of viewing points is a predetermined value. For the following channels (that is, channels not registered in the viewing frequency list 60), channel selection based on the viewing frequency order selection button 42 is omitted.

以上のように本実施形態のＴＶ放送信号受信装置１によれば、メモリ１７に記憶された各チャンネルの視聴ポイント数に基づいて視聴頻度順位を算出し、ユーザによって視聴頻度順選局ボタン４２が操作された際に、この視聴頻度順位に基づいて視聴頻度が高いチャンネルから順番に選局させ、視聴頻度が所定値以下のチャンネルについては視聴頻度順選局ボタン４２に基づく選局を省略したので、ユーザは複雑な操作をすることなく視聴頻度順選局ボタン４２を操作するだけで、視聴頻度が高いチャンネルのみを選局することができる。   As described above, according to the TV broadcast signal receiving apparatus 1 of the present embodiment, the viewing frequency ranking is calculated based on the number of viewing points of each channel stored in the memory 17, and the viewing frequency order selection button 42 is selected by the user. When operated, the channels are selected in order from the channel with the highest viewing frequency based on this viewing frequency ranking, and the channel selection based on the viewing frequency order selection button 42 is omitted for the channel whose viewing frequency is a predetermined value or less. The user can select only a channel with high viewing frequency only by operating the channel selection button 42 in order of viewing frequency without performing complicated operations.

また、メモリ１７に記憶された各チャンネルの視聴履歴に基づいて視聴頻度順位が算出され、この視聴頻度順位に基づいて、視聴頻度順選局ボタン４２が操作された際に行われる選局動作が制御されるので、視聴頻度の高いチャンネルを「お気に入り」として登録させる等の特別な作業をユーザに強いることなく、ユーザは視聴頻度順選局ボタン４２を操作するだけで簡単に視聴頻度の高いチャンネルを選局することができる。   In addition, the viewing frequency ranking is calculated based on the viewing history of each channel stored in the memory 17, and the channel selection operation performed when the viewing frequency order selection button 42 is operated based on the viewing frequency ranking. Since the control is controlled, the user can easily operate the channel with the high viewing frequency simply by operating the channel selection button 42 in order of the viewing frequency without forcing the user to perform a special operation such as registering the channel with the high viewing frequency as “favorite”. Can be selected.

また、同じチャンネルが所定時間以上連続して視聴された場合にのみ視聴ポイントを１ポイントずつカウントして各チャンネルの視聴履歴を記憶するので、選局された各チャンネルの回数をカウントすることにより視聴履歴を記憶する場合と比べて、本来、視聴履歴としてカウントされるべきではないザッピング（テレビコマーシャル等の最中にチャンネルを次々と変える行為）等による選局が視聴履歴としてカウントされることを防止することができる。また、視聴頻度をポイント化して所定時間毎にカウントすることで、視聴した時間をそのまま視聴履歴として記憶する場合と比べて、記憶すべき情報量を削減することができる。   Also, only when the same channel is viewed continuously for a predetermined time or more, the viewing points are counted one by one and the viewing history of each channel is stored, so viewing by counting the number of times each channel is selected Compared to the case of storing history, channel selection due to zapping (an act of changing channels one after another during TV commercials) that should not be counted as viewing history is prevented from being counted as viewing history. can do. Also, by making the viewing frequency a point and counting every predetermined time, the amount of information to be stored can be reduced compared to the case where the viewing time is stored as it is as a viewing history.

また、視聴頻度順位は、所定周期毎に、所定期間分の視聴ポイント数を合計することにより算出され、メモリ１７に記憶されているので、制御部１８は、ユーザによって視聴頻度順選局ボタン４２が操作される毎に、改めて視聴頻度順位を算出するための処理を実行する必要がなく、視聴頻度順選局ボタン４２に基づく選局動作時の処理負担を軽くすることができる。   Also, the viewing frequency ranking is calculated by summing the number of viewing points for a predetermined period for each predetermined period and stored in the memory 17, so that the control unit 18 selects the viewing frequency order selection button 42 by the user. Each time is operated, there is no need to execute a process for calculating the viewing frequency order again, and the processing load during the channel selection operation based on the viewing frequency order selection button 42 can be reduced.
